长滩港2025年排放清单：最繁忙之年单位集装箱排放创历史新低，柴油颗粒物一年降7%
位于加州洛杉矶县的 Long Beach 港务局11月11日发布2025年排放清单：该港在有记录以来最繁忙的一年里，单位集装箱排放降至历史最低，港口相关空气污染排放全面下降。
清单显示，与上一年相比，柴油颗粒物下降7%，氮氧化物下降9%，二氧化硫下降9%，温室气体下降6%。港务局把减排归因于零排放设备的战略投入、岸电使用增加，以及更清洁船舶到港更频繁。
自2017年该港与相邻的洛杉矶港共同通过《清洁空气行动计划》更新版以来，柴油颗粒物累计下降13%，氮氧化物下降34%，硫氧化物下降29%；同期集装箱吞吐量大增31%，温室气体则上升9%。
Long Beach 港务委员会主席 Steven Neal 表示，调查结果证实了该港的一项基本原则：港口完全可以一边做全国强劲的就业引擎，一边保护环境，港方将继续坚定削减排放、服务社区。港务局首席执行官 Noel Hacegaba 博士表示，该港正全力建设零排放的「未来之港」，最新清单表明方向正确。
2025年是 Long Beach 港有记录以来最繁忙的一年，码头共处理近990万个标准箱；这一年也是该港开创性的《绿色港口政策》通过20周年。今年还是《清洁空气行动计划》20周年：自2005年以来，柴油烟尘下降91%，氮氧化物下降70%，硫氧化物下降98%，温室气体下降9%，集装箱吞吐量则增长47%。
清单其他要点包括：2014年或更新款卡车占比升至95%的历史最高水平，短驳车队中2%为零排放车型；靠泊船舶使用岸电与排放控制驳船的比例增加11%；21%的到港船舶装有最清洁的 Tier III 发动机；21%的货物装卸设备为零排放型号。
为加速迈向无碳未来，该港明年将推出一批新举措，包括鼓励提高零排放卡车使用率的卡车利用激励计划、扩大零排放卡车购车券计划、更新绿色船舶激励计划以吸引更清洁的船舶到港，并继续推进零排放基础设施规划。年度排放清单由美国环境保护署、加州空气资源委员会与南海岸空气质量管理区共同审查。

Port of Long Beach Emissions Hit Record Low Per Container in Busiest Year: Diesel Particulates Down 7% in 2025 Inventory
LONG BEACH, Los Angeles County, California — The Port of Long Beach on November 11 released its 2025 emissions inventory, finding that emissions per container fell to an all-time low in the busiest year in the port's recorded history, with across-the-board reductions in port-related air pollution compared with the prior year.
Single-year reductions include diesel particulate matter down 7%, nitrogen oxides down 9%, sulfur oxides down 9% and greenhouse gases down 6%. The port credited strategic investments in zero-emissions equipment, greater use of shore power and more frequent visits by cleaner ships.
Since the 2017 update of the Clean Air Action Plan, adopted with the neighboring Port of Los Angeles, diesel particulates have decreased 13%, nitrogen oxides 34% and sulfur oxides 29%, while container throughput rose 31% and greenhouse gases increased 9% over the period.
"These findings confirm one of our foundational principles — that it's possible to serve as a vibrant and strong jobs engine for the nation while protecting the environment," said Long Beach Harbor Commission President Steven Neal. Port CEO Dr. Noel Hacegaba said the port is focused on building the Port of the Future, a safe, resilient and zero-emissions port, and that the latest inventory shows it is on the right track.
Last year was the port's busiest on record, with terminals handling nearly 9.9 million twenty-foot equivalent units, and it was also the 20th anniversary of the port's Green Port Policy. This year marks the 20th anniversary of the Clean Air Action Plan: since 2005, diesel soot has decreased 91%, nitrogen oxides 70%, sulfur oxides 98% and greenhouse gases 9%, while container throughput increased 47%.
Other highlights of the 2025 inventory: trucks of model year 2014 or newer reached a record 95% of the drayage fleet, with 2% zero-emissions models; use of shore power and emissions-control barges for ships at berth increased 11%; 21% of vessel calls had Tier III engines, the cleanest available; and 21% of cargo-handling equipment was zero-emissions.
In the coming year the port will launch a truck utilization incentive program, an enhanced zero-emissions truck voucher program, an updated Green Ship Incentive Program and continued work on a zero-emissions infrastructure plan. The annual inventory is reviewed by the U.S. Environmental Protection Agency, the California Air Resources Board and the South Coast Air Quality Management District.
